<p>I’m still a pre-frosh, so I don’t know all the specifics, but I’ll try to help. It’s free if you’re in Steinhardt; otherwise you have to pay about $70/semester (but this works out to less than $5 per lesson). The lessons are taught by grad students, I think. There is more information about lessons in [url="<a href="http://community.livejournal.com/nyu/921914.html"]this[/url">http://community.livejournal.com/nyu/921914.html"]this[/url</a>] nyu livejournal entry. If you have an account, you could ask for more information in that community as well.</p>
